The General Purpose Smart Relay Switch (GPSRS) is a programmable relay device that provides automatic control for a myriad of applications.  Compatible with reed switches, toggles, pushbuttons, etc., the GPRS can accept any switch or sensor device having normally open or normally closed contacts.  Programmed with onboard DIP switches, the unit can be configured to activate or de-activate an external device or machine when a state change trigger occurs on one of the inputs.  The device can be returned to its normal operating condition when the switch sensor returns to the pre-triggered state and/or a delay period has elapsed.  DIP switches allow you to configure operational mode and delay parameters.

The GPSRS provides connections for 4 wired inputs.  Each input can accept a single switch sensor or can be wired in a zone configuration with multiple switch sensors in series or parallel.  Typical switch sensors include reed switches, pushbuttons, toggle switches, and similar devices.  (Note that the GPSRS can be configured to accept either normally-open or normally-closed switches.)  Wired inputs are also compatible with TTL signals.  (Note: Wired sensor cabling should be limited to 100 ft. max. at each input.  Twisted-pair shielded cables recommended.) 

And, with an optional RF receiver, the GPSRS also accepts input from compatible wireless door/window sensors, motion detectors, and key fob transmitters.  The wireless option provides inputs for up to 10 additional devices.  Even deploy a combination of both wired and wireless sensors.
